(3,4) And they can bind to erythrocytes,simultaneously with immune factors, causing hemagglutination and anemia. (5)Of the 119 known dietary lectins, about half are panhemagglutinins, clumping allblood types. The remainder are blood-type specific.
Two of the four cells will contain one recombinant chromosome. In eukaryotic cells, crossing over can also occur during mitosis. Somatic cells (non-sex cells) undergo mitosis to produce two distinct cells with identical genetic material.
Further genetic variation comes from crossing over, which may occur during prophase I of meiosis. In prophase I of meiosis, the replicated homologous pair of chromosomes comes together in the process called synapsis, and sections of the chromosomes are exchanged. You can see that after crossing over, the resultant chromosomes are neither entirely maternal nor entirely paternal, but contain genes from both parents. Synapsis and crossing over occur only in meiosis.
